Using Visual Studio 2019, VB Windows Forms App(.Net Framework) template, my students are building projects using multiple forms, pictures (as background images and in picture boxes) and timers. When they have two or more pictures, the programs crash irretrievably.
The error message is:
Error while trying run project: (path to project location) Access is
denied.
Even if they remove the pictures, the error remains and the program no longer works. I never experienced this problem when we were using VB2015.
My student assistant tried to replicate the problem on (Vis Studio 2019) his home computer and couldn't.
If you're using an antivirus you may add an Exception to the project path.
You may also try to run VB2019 as Administrator to see if that was the problem, click on the VS2019 icon using the right button of the mouse and then click on Execute as Administrator.
Anyone can help me with below error? It looks like it has something to do with different versions but I am not able to solve it. I followed different instructions like: Installing the NuGet package for the WinForms than adding the dll via .NET Framework components.
When I drag and drop the ReportViewer onto a Form it gives me the below error.
This is what I did and it worked well for me:
1- Installed Microsoft Rdlc Report Designer for Visual Studio
2- Opened Visual Studio and created a new project using Visual Basic > Report Application template. (You can also search for it using top right search box)
3- From the warning dialog clicked Trust
4- Cancelled Report Wizard (I just didn't want to create report initially, you can create.)
5- Rebuild the solution.
You are all set. You can add a new Report and design it in VS and show it in ReportViewer. If you open Form1 you can see a ReportViewer there.
To add it to toolbox, you can click on Choose Items and then Browse your solution directory and from the NuGet package folders go to report viewer package folder and select Microsoft.ReportViewer.WinForms.dll.
For more information on how to add report viewer control to a form see Integrating Reporting Services Using ReportViewer Controls - Get Started.
I'm just getting started creating reports for a VB.NET application in Visual Studio. I get that you have to put a report viewer control on a form and bind the report to it when running the application but when developing the report, how do you just preview it without running the app and then the report? I have it open in design mode but for the life of me I can't figure out how to preview it while developing.
Thanks
I have a website made with vb and c#. I open the project in Visual Studio 2010 and there are no problems.
My problems start when I try to debug it. I have this error:
Could not load type 'projectName.Global
Also I need to convert it into a web application but when I do right-click on the project this option is not there.
I did all settings in IIS but I always have this error and I cant convert it
If it is not clear tell me, I will try to improve my question.
I just installed Visual Studio 2012 Ultimate and I am trying to create a managed code extension project for Excel 2010 (32 bit Office Professional Plus). I have tried using the .NET 4.0 template contained in VS Ultimate for an Excel 2010 workbook. When I create the project everything looks fine until I run it.
Excel opens and I get the error message "The customization assembly could not be found or could not be loaded. You can still edit and save the document. Contact your administrator or the author of this document for further assistance." The details section is blank.
I have tried everything I could think of to figure this out and I have run out of ideas. I removed all addins from Excel except for the VSTO Design-Time Adaptor for Excel. I removed all personal macros. I set every directory I could think of to "trusted" in Excel and lowered the security settings for all options to "enabled (not recommended)". I completely uninstalled Visual Studio and re-installed. There are no errors or warnings showing up in Visual Studio. I also checked to make sure ".NET Programmability Support" was installed for my copy of Microsoft Excel.
I would link my code but I haven't written anything. I can't even get the default template to load when I run the project. A few others at work have the same setup as me and VSTO runs fine for them using the same steps. I even had someone send me a working project but it gives me the same message when I try to run it.
Is there anything else I can check to see where the problem is occurring? I tried setting break points in the project but it is failing before it gets to any of them.
Thanks so much for your help.
I've run into the same problem with Visual Studio 2010.
I isolated the problem to an SSRS reporting link we were trying to run from the add-in. I removed all the reporting stuff (service reference, sub-dirs, etc.) - the add-in runs fine.
We just ran into this and discovered that a method had a system exception that was not handled. It was hard to track down but once the culprit method had an exception handler the customization finished loading properly.
